Description: Lorediplon is a nonbenzodiazepine of the pyrazolopyrimidine family that is being pursued as a treatment for insomnia but has not completed development. Lorediplon demonstrated a dose-dependent improvement in sleep, whereas zolpidem showed a more sustained WASO effect. No next-day hangover effects were observed. These sleep effects are also consistent with the pharmacokinetic profile of lorediplon. These results warrant clinical trials in patients with insomnia.
